CORPORATION OF NEW YORK WINDOW SASH Application filed September 21,1929.

- to cleaning the outer surface of the glass of a window to slide thesame vertically in order to allow the person about to clean the glass toperform the cleaning operation from the outer slide, one of the objectsof this invention is to provide an inwardly swingable member forcarrying the glass, so that both sides of the window may be safelycleaned while the cleaner remains inside the building.

Another object of the invention is the provision 'of interchangeablewindow members for carrying glass panels, so that the inconvenience andloss of time sustained by the personnel of commercial andotherbuildings, during periods of inclement weather whenit has been necessaryfor a window cleaner to retain windows in an open condition forprolonged periods, may be removed. An extra, clean window section maytherefore be carried to replace a soiled or damaged section, while thelatter is being cleaned or repaired.

A further object of the invention is to provide, for a window, havingfixed and openable sections, both of which are partly exposed to theelements, an interposed strip of resilient material in connection withone of the sections, so that a weather proof closure may be effected onclosing the openable section.

Other objects and advantages of the invention will be hereinafterspecifically pointed out, or will become apparent, as the specificationproceeds.

With the above indicated objects in view, the invention resides incertain novel constructions and combinations and arrangements of parts,clearly described in the following specification and fully illustratedin the accompanying drawings, which latter show an embodiment of theinvention as at present preferred.

Figure 1 is a front elevational view of a window having the presentinvention in corporated therein.

Serial No. 394,252.

Figure 2 is a vertical sectional view on the hne 22 of Figure 1.

Figure 3 1s a horizontal sectlonal new on the line 3-3 of Figure 1.

Figure 4 is a rear plan view of a frame carrying a glass panel therein.

Figure 5 is a perspective view of a looking bolt.

Figure 6 is an elevational view of a retaining latch, partly sectional.

Referring particularly to the drawings by reference characters, thenumeral 10 designates a window casing, in which a pair of sections 11and 12 are slidably mounted, counterweights, pulleys and flexiblesupporting elements, not shown, being provided.

As the construction of the sections 11 and 12 are similar, a descriptionof one is equally applicable to the other. In order to render both sidesof the glass panel 13 easily ac,- cessible, I provide a swingable member1 1, to the front metal frame 15 of which two of the retaining plates orhinges 16 are attached as by rivets 17, while the other two plates ofsaid hinges, secured in mating relation with the first mentioned platesby re movable pins 18, are similarly held rigid with a fixed frame orreceiver 19 of angle metal, which is attached as at 19 to the outerboundary frame of the section 12, said 0 latter frame being preferablyof wood.

The frame 15, the respective top, bottom and lateral members of whichare metallically joined at the corners, is substantially T-shaped incross section, there being a web 20 and a flange 21 against the innersurfaces of which the outer edges of the panel 13 find a seat; and arestricted flange 22 extending outwardly as far as the outer surface ofthe receiver 19, while the inner surface of one flange 23 of thereceiver fits loosely against the outer surface of said web. In order toseal the joint between the frame of the section 12 and the receiver, afilling 0f putty 19 or the like is provided.

Disposed between the panel 13 and the flange 24 of the receiver 19 is aresilient gasket or member 25, preferably of soft rubber, while a flange26 of said asket extends outwardly over the edge 0 the web 20, therebyforming a thoroughly watertight and airtight joint when the member 14 isclosed, there being a lock bolt 27, to be hereinafter referred to, whichmaintains the required pressure between the member 14 and section 12.The gasket 25 may consist of four sections, which rest in mutualengagement at the corners of the frame 14, and which are held in placeby clamping plates 28, each of which is provided with a tapped hole toreceive the terminal of a screw 29. lVhile said plates are countersunkin the rubber, the corners of the glass panel are cut away toaccommodate said screws.

Slidable vertically on certain occasions, the sections 11 and 12, whichare rigid against fore and aft movement, are also held rigid againstslidable movement by another bolt 27. In order to adjustably retain themember 14 in any selected location, between the closed and openpositions, the latter position being indicated in dot and dash lines inFigure 8, I provide latch mechanism which includes, terminally attachedat 30, an arcuate toothed arm 31, a continuation of which is attached at33, these attachments being on the section 12, while a dog or member 34is pivoted at 35 on the frame 15.

Said latter member is provided at one end thereof with a detent tooth36, which engages with any selected tooth of the arm 31. A housing 37carries a spring pressed pin 38, a hemispherical or rounded end of whichengages in one of two apertures 39 in the opposite end of the pivotedmember. It will therefore be seen that, on movement of the pivotedmember, as by its handle or pin 40, the tooth 36 is held either engagedwith or clear of the teeth of the arm 31, the disengaged position beingindicated in dot and dash lines in Figure 6. On the window sec tion 11,I prefer to mount the latch mech anism 34 at the top of the swingablemember 14. This latch mechanism may be taken as representing anysuitable means for performing the same function.

The lock bolt 27 hereinbefore referred to includes a base plate 41which, to accommodate a slidable rod 42 is transversely cambered at 43.This rod, has preferably formed therewith, an arm 44, which carries amanipulating terminal 45, and as the cambered portion 43 and lower endof the plate 41 have communicating transverse and longitudinal slots 45and 46 therein, said rod, the 'base of which is movable in thetransverse slot for locking or unlocking the de vice, is engageable inthe slot 46 for holding the device in the locked position. In saidlatter position the arm 44 lies flush with the plate 41 and finds a seaton any supporting structure on which the base plate is mounted, therebeing apertures 47 in the plate for reeeiving fastening elements. Toreceive the terminal of the rod 42 a keeper plate 48 is provided.

While the frame section 12 is constructed to receive the metal frame 19,a swingable member 14 may be mounted in an existing window, the slidableframe of the latter being altered to receive a metal frame; like thatshown at 19, on which to mount a swingable member 14; and, although asingle member 14 is shown in the frame 12, two or more members may, ofcourse, be mounted in one supporting frame.

The hereinbefore described construction admits of considerablemodifications without departing from the invention; therefore, I do notwish to be limited to the precise arrangements shown and described,which are, as aforesaid, by way of illustration merely. In other words,the scope of protection contemplated is to be taken solely from theappended claim, interpreted as broadly as is consistent with the priorart.

lVhat I claim is In a window construction, a casing, sections slidablymounted in said casing a frame of angle metal for each section and beingfixedly secured therein, a movable metal frame for each section andcooperating with the fixed frames, the movable metal frames beinghingedly secured to the sections, latching means for said movable metalframes and holding the same at various angles with respect to the fixedframes, transparent panels for the movable frames, a gasket for eachpanel and surrounding the same, clamping plates for holding the gas ketsagainst the panels, securing means passing through the movable frames,gaskets and clamping plates respectively for seem-- ing the panels tosaid movable frames, said movable frames being substantially T-shape incross section to provide webs engageable with the outer edges of thepanels and fixed frames respectively, flanges engageable with a side ofthe panels, restricted flanges formed with the flanges first mentionedand receiving one of the angle portions of th fixed frames when themovable frames are disposed in closed position, and means for fasteningthe movable frames accordingly.

In testimony whereof I hereby affix my signature.

RALPH CAIAZZO.
